Transient Crystal Size Distribution in DTB and FC Crystallizers

This work deals with the transient analysis of crystal size distribution (CSD) for imperfectly mixed draft tube baffled (DTB) and forced circulation (FC) crystallizers. The DTB and FC crystallizers are described by the Compartmental and Mixed models respectively. Monte Carlo (MC) scheme has been employed for simulation purposes. The simulation results have been compared with the available experimental data of BENNETT and VAN BUREN for continuous urea crystallizers.

Evidence of syntactic working memory usage in MEG data

While reading times are often used to measure working memory load, frequency effects (such as surprisal or n-gram frequencies) also have strong confounding effects on reading times. This work uses a naturalistic audio corpus with magnetoencephalographic (MEG) annotations to measure working memory load during sentence processing. Alpha oscillations in posterior regions of the brain have been found to correlate with working memory load in non-linguistic tasks (Jensen et al., 2002), and the present study extends these findings to working memory load caused by syntactic center embeddings. Moreover, this work finds that frequency effects in naturally-occurring stimuli do not significantly contribute to neural oscillations in any frequency band, which suggests that many modeling claims could be tested on this sort of data even without controlling for frequency effects.

Commentary on Fine Arts Copyright Act 1862

Legislation conferring copyright protection on paintings, drawings, and photographs for the life of the author plus a seven year post mortem term. The Act was also innovative in de-coupling the copyright term from the event of publication, in providing artists with a new form of ‘moral rights' protection, and in introducing the concept of "originality" as the standard threshold for copyright protection.
The commentary explores the background to the legislation, and in particular, the international copyright regime, the nature of the art market in eighteenth and early nineteenth centuries, the role of the Society of Artists in lobbying for legislative protection, and the impetus which the International Exhibition provided for securing the same. The commentary also considers how the 1862 Bill, in its earliest incarnation, incorporated elements that would have signalled a radical departure from established copyright norms. In particular, the Bill proposed: that copyright protection should not be contingent upon registration; and that protection should be offered on a universal basis, regardless of an artists' nationality, and regardless of where the work in question was created.
